Abstract

The invention discloses a nano calcium carbonate-containing wood modification treatment agent comprising the following components by mass: 3%-6% of methylsilicone oil, 0.5%-1% of glycerin triglycidyl ether, 8%-15% of nano calcium carbonate, 1%-2% of sodium dodecyl sulfate, 6%-10% of magnesium chloride, 1%-4% of ammonium heptamolybdate, 2%-5% of nano titanium dioxide, 3%-6% of didecyldimethylammonium chloride, 5%-8% of sodium octoborate, 2%-5% of methyl pentenone, 1%-2% of sodium polyacrylate, 2%-6% of polyethylene glycol (PEG) and 30%-65% of water. The beneficial effect is that the nano calcium carbonate-containing wood modification treatment agent has the advantages of good permeability, strong resistance to erosion, good heat resistance, and the like, and has practical effects of good corrosion prevention, flame retardance, toughening and strengthening, wear resistance, low tendency to crack and durability and the like.

Description

technical field [0001] The invention relates to the technical field of wood treatment agents, in particular to a wood modification treatment agent containing nanometer calcium carbonate. Background technique [0002] Wood is a renewable, recyclable and naturally degradable green material and biological resource. It has the advantages of beautiful texture, natural color, comfortable texture, good plasticity, and easy processing. However, wood also has some defects, such as dry shrinkage and wet swelling due to changes in moisture content, resulting in changes in the size and shape of components and reduction in strength, easy to mildew and decay, easy to be eaten by insects, easy to burn, etc. These defects will greatly limit the application effect and application field of wood. In order to obtain high-performance and high-value-added wood products, it is usually necessary to make necessary functional improvements to the wood before it is used, so as to overcome its defects ...
